Abstract

PURPOSE: To manufacture the title urethane foam, by reacting a polyol with a polyisocyanate in the presence of a catalyst, a foaming agent, and a flame-retardant comprising fine powder of sparingly soluble ammonium polyphosphate.
CONSTITUTION: A flame-retardant rigid urethane foam having improved water absorption is prepared by reacting a polyol with a polyisocyanate in the presence of conventional catalyst, foaming agent, foam stabilizer, etc., and a specific flame retardant comprising fine powder of sparingly soluble ammonium polyphosphate [(NH4)n-m+2HmPnO3n+1 wherein n is integers having an average value of ≥20; average value of m/n is about 0.7W1.1; and the maximum value of m is n+2] wherein the content of particles having diameter of ≤30μ is ≥90wt%.
